Application led February 6, l1912. Serial No. 675,723.

Be it known-that I, J oHN T. Horn, a citizen of the United States, residing at Kan'- sas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in VacuumfCleaner Tools, of which the following is a specification.

This invention relates to vacuum cleaner tools and has for its object to produce a swivel airtight connection between the sha-nkof the tool land the handle whereby the operator is enabled to obtain access below objects supported three or four inches above the floor.

With this general object in view and others as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood 'reference is to be had to the accompanying drawing, in which- Figure 1, is a top plan view of a vacuum cleaner tool embodying my invention. Fig. 2, is a side elevation of the same. Fig. 3, is a central vertical section on the line III-III of Fig. 1. Fig. 4, is a section on the line IV--IV of Fig. 1.

In the said drawing, 1 is the tool mouth piece of well-known type, for movement over a floor oI carpet to pick up dust lint or other dirt therefrom, 4and 2 is the tubular shank of the mouth piece, The shank is diametrically reduced at its rear end to provide a rearwardly-disposed shoulder` 3, and said shoulder is provided with a circular channelL 4, in which is secured a gasket 5. A similar asket 6 is secured in a circular channel 7 in the front end of the shank, and said shank Ais provided outward of the last-named gasket and preferably vertically below the axisV of the shank with a longi tudinal channel 8, and between the gaskets with a circumferential channel 9 communicaing with the front or inner end of channe 8.

10 -is a tubular handle and secured upon the front end of the same is a collar 11, which for about half its length, is diametrically enlarged internally to form a forwardly-disposed shoulder 12, to bear against gasket 6, yand to fit over the reduced portion of the shank and 'bear against gasket 3, and extending radially into the enlarged portion of the collar vertically above its axis,

is a sc rew or pin 13, equipped at its inner end with a ro ler 14, engaglng the circumferential channel 9 ofthe shank when the V4handle is attached to the mouth-piece.

To secure the handle to the mouth-piece, it is first turned to dispose roller 14 in line with the channel 8. yThe reduced' portion of the shank and the collar are then fitted telescopically together and the front end of the handle extends into the shank to make the connection more stable and effective. The handle is then turned to cause the roller to enter the circumferential channel 9, the endwise engagement between the shank and collar being made air-tight through the interposition of the it will be impossib e for any air 'to escape from the mouth-piece through the joint between the same and the handle, the latter being connected as customary, by a flexible tube or hose to a suction apparatus, not shown.

The tool is manipulated in the usual manner and because of the bent form of the handle, the mouth-piece can be slipped under an object, such as a desk or side-board standing only a few inches from the floor. To accomplishthispurpose the handleis .turned without lifting the mouth-piece from the floor, until the rear end of the former is about the same Vheight as its front end,

being turned a quarter revolution to accomplish this purpose.

Where it is desiredto manipulate the tool along the side or end of an object, represented by dotted lines a, assuming the space is so restricted that it cannot be accomplished with the tool in the position shown in full lines Fig. 1, the handle can be turned slightly so as to dispose it at an angle to such line as shown by dotted lines saidgure, as by this adjustment of the handle, its curved lower portion 15 is bowed around the corner of the object and the tool stands at right angles to the end of the latter.

It will be apparent that it isim ossible for the mouth-piece to become acci entally detached from the handle while in use, as it can not turn the half revolution in one direction, necessary to bring roller 14 in line with channel 8, as the limit of its rotatable adjustment necessary in the manipulation of the .mouth-piece is a quarter revolution toward one side or the other, and in practice the roller 14 will be 'disposed at a point in channel 9 diametrically opposite askets 5 and 6, so that tion shown and described as obvious modifiparentthat I have produced a vacuum channel 8 when the handle and mouth-piece occupy A.their normal relation, as shown by full lines in the drawing.

From the above description it will be apcleaning tool embodying the features of advantage enumerated as desirable, and I wish it to be understood that while I have illustrated and described the preferred embodiment of the invention, I do not desire to be restricted to the exact details of construcgroove and with a longitudinal groove communicating with said annular groove and extending to the end of the reduced portion, a collar member fitting rotatably on said reduced portion, annular gaskets interposed between the abutting portions of said members, a pin secured in said collar member, and a roller mounted on the inner end of the pin and adapted to be passed through the longitudinal groove into the annular groove, thereby forming a swivel air-tight connection between said members.

In testimony whereof I aftiX my signature, in the presence ot two witnesses.
